Low power RF quadrature modulator IC offer flexibility coupled with high performance
The CMX971 is a high performance quadrature modulator featuring a wide operating frequency range, excellent modulation accuracy and low power consumption. The device can be programmed via a simple serial bus or working in ‘direct control’ mode, which does not require connection to a serial controller. In both modes programmable features include a local oscillator divider ratio (divide by 2 or 4) and linearity versus noise optimization. The device can operate over the RF output range of 20 MHz – 1 GHz with a power supply voltage of 3.0 V – 3.6 V.
The CMX971’s quadrature architecture supports a wide range of modulation formats and standards. The device provides translation from baseband I/Q signals to a modulated RF signal. The differential inputs are ideal for direct connection to standard modems and interface ICs such as CML’s CMX7163, CMX7164, CMX910, CMX981 and CMX7861.
The CMX971 is available now, comes in a small, RF-optimized 16-lead VQFN package, measuring 4 mm x 4 mm x 1 mm. The device has minimal external components, making it ideal for space-constrained applications. The CMX971 offers the designer high performance, flexibility and fast time-to-market.
